Title: Liq. slip grinding agents - comprise water, surfactant and polyethylene glycol solubilising agent
IPC: B24B31/14
Filed: 1990-09-15
Abstract: Liq. slip grinding agent is composed of above 50% of a surfactant, water and 2-15% of a solubilising agent consisting of polyethylene glycol with an average mol. wt. of 200-400. A typical compsn. comprises 40% water, 55% surfactant mixt. and 5% polyethylene glycol. USE/ADVANTAGE - The slip grinding agents are used during slip grinding, esp. vibration slip grinding, to intensify the grinding action and/or to optimise the ground surface. Known slip grinding agents use low alcohols as solubilising agents for the surfactant, but these have the disadvantages of flammability, toxicity and of lowering the corrosion resistance of the material being ground. These disadvantages are now overcome by using a low polyethylene glycol as solubilising agent. (2pp Dwg.No.0/0)

Title: Combustion heat conversion system - has adiabatic compression and expansion of working gas
Inventor: BERGTER ROLF
IPC: F02G5/02
Filed: 1990-12-31
Abstract: The process is for conversion of combustion heat into mechanical work. A working gas at a temp. T1 and pressure P1, is taken-in, and compressed, until it reaches the temp. T2 and the pressure P2. The gas is heated to the temp. T3 by a heat exchanger process. - The temp. of the air required for combustion is brought to a temp. level T5 in a heat exchanger, in counterflow to the flow direction of the combustion products, with T1 is less than or equal to T5 is less than or equal to T7. The temp. of the combustion products drops in the heat exchanger from T7 to T8, with T1 is less than or equal to t' is less than or equal to T7 and T2 is less than or equal to T7 is less than or equal to T6, before this air is used to burn a fuel. The combustion products at the temp. T6, heat the working gas in the heat exchanger, from an initial temp. T2 to T3; while the temp. of the combustion products drops from T6 to T7. Due to its expansion, the working gas performs mechanical work, and then has the temp. T4 and the pressure P1. - (Dwg.2/4)

Title: Interlocking system for manually operable rotating shafts of power breaker switch - uses shaft-mounted eccentric cam to prevent locking bar from inhibiting access to end of shaft
Inventor: MATHES WERNER
IPC: H01H9/28
Filed: 1991-04-05
Abstract: The interlocking system comprises a shaft (1) with an eccentric cam (7) that bears on a locking bar (4), the position of which either permits or blocks a manual operating lever (2) from engaging on the end of the shaft. The locking bar is supported by upper and lower metal pressings (8b,8c) and is located behind an earthed front panel (8). A portion of the locking bar (4a) inhibits a peg (3a) from moving along the shaft when in the blocking position, preventing a spring-loaded dog-gear (3) from engaging with the shaft when the operating handle (2) and associated driver are inserted into the shaft end slot. In the open position, the shaft cam forces the bar downwards, enabling the dog-gear to slide into position and allowing the operating handle to couple onto the shaft. The locking bar is reset by a hinged plate (5) with an operating arm (5a) that engages in a slot (10) in the locking bar. When the shaft cam is rotated to the closed position and the operating handle removed, applying a force (6) to the plate through a slot (12) in the front panel slides the bar upwards (11), setting the mechanism to the blocked position. USE/ADVANTAGE - For medium voltage power breaker. Provides simple, reliable locking mechanism that requires low operating force.

Title: Long service life bearing - consists of two coaxial rings joined by elastomer bellows type creased member with elastic protective stops and locked in outer ring
Inventor: SCHWERDT HANS-WERNER
IPC: F16C27/06
Filed: 1991-12-04
Abstract: A bearing has two coaxial outer support rings which are joined elastically by a radial bellows type member whose cross-section has at least one radial crease and which is not axially longer than either ring, and at least one cushioning stop is located beyond each crease. The bellows type member is made of thermoplastic elastomer; the cushioning stop extends radially from one ring towards the other and partially overlaps the crease concerned. ADVANTAGE - The design has a very long service life compared with that of existing designs. At the same time it also functions more effectively. In an example the two rings (1, 2) joined together radially by the bellows type member (3) which has axially disposed creases (3.1, 3.2) and has also cushioning stops (5, 6). These stops (5, 6) assume the positions shown dotted when the bearing is dismantled but, when heated and deformed recover the positions shown at right angles to the axis (7). The bearing preferably has a number of these stops (5, 6) round the circumference. They protect the creases (3.1, 3,2) from damage or mechanical stresses if the bearing is radially deflected severely.
